FARMINGTON — A third suspect has been arrested in a mysterious shooting incident reported last Friday, Jan. 11, police announced this morning.

Joshua Dionne, a North Bewick, Maine, man, is the third suspect who was arrested in this incident. He has been charged with robbery and conspiracy to commit robbery, though he is currently being processed in Maine for a parole violation and being a fugitive from justice.

Matthew T. Roaf, 21, of 33 Second Street, Lebanon, Maine, reportedly turned himself in to the Farmington Police Department on charges of robbery and conspiracy to commit robbery after he was released from Brigham and Women's Hospital in Boston.

Following last Friday's incident, another arrested suspect — Stephen Roy, of Lords Court, in Somersworth — was treated for a gunshot wound to the head at York Hospital in Maine around the same time as Roaf was reportedly treated at Portsmouth Regional Hospital before his transfer to Boston.

Investigators from the Farmington Police Department and New Hampshire State Police say they are actively investigating the shooting but will not comment further on the circumstances leading up to the shooting or the status of the investigation except to say that it is progressing. They say additional details will be released when it is determined that releasing this information will not jeopardize or interfere with the investigation.

If anyone has information about this incident, they are urged to contact Detective Brian Driscoll at 603-755-2731, ext. 105. Information can be given anonymously by calling the department's Crimeline at 603-755-9797.
